更新:我发现为什么它一直在加载相同的视图。我现在解决了这个问题这是一个错字
ControllerForSplitViews.m
- (id)init
{
self = [super initWithNibName:@"ControllerForSplitViews" bundle:nil];
if(UIInterfaceOrientationIsLandscape(self.interfaceOrientation)){
self.view = landscapeView;
}
if(UIInterfaceOrientationIsPortrait(self.interfaceOrientation)){
self.view = portraintView;
}
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(orientationChanged:) name:@"UIDeviceOrientationDidChangeNotification" object:nil];
return self;
}
这很有效。
现在问题。加载并运行视图时,我更改方向并从同一个nib文件加载不同的视图,修复:但是一旦我这样做,其他UI元素就会消失,只保留我的横向视图的ui元素,当我再次旋转设备它不会再次加载我的纵向视图?有任何建议可能会发生这种情况吗?
-(void) orientationChanged:(id)object
{
if(UIInterfaceOrientationIsPortrait(self.interfaceOrientation))
{
self.view = portraintView;
}
if(UIInterfaceOrientationIsLandscape(self.interfaceOrientation))
{
self.view = landscapeView;
}
}
新问题,每当我更改方向时,它都会加载相反方向的视图

好的,所以我找到了一个有效的修复程序,但我不知道为什么我的原始代码无法正常工作:
卸下:
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(orientationChanged:) name:@"UIDeviceOrientationDidChangeNotification" object:nil];
卸下:
-(void) orientationChanged:(id)object
{
if(UIInterfaceOrientationIsPortrait(self.interfaceOrientation))
{
self.view = portraintView;
}
if(UIInterfaceOrientationIsLandscape(self.interfaceOrientation))
{
self.view = landscapeView;
}
}
变化:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
if(((interfaceOrientation == UIInterfaceOrientationLandscapeLeft) ||
(interfaceOrientation == UIInterfaceOrientationLandscapeRight))){
self.view = landscapeView;
}else if(((interfaceOrientation == UIInterfaceOrientationPortrait) ||
(interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown))){
self.view = portraintView;
}
return YES;
}
现在它完美无缺
